Cosmo,
The shavings were worse in the OD housing than they were in the main case. Main case had a lot of very fine shavings that were mostly contained in the sump below the splash plate. The OD side was a different story. Lots of flakes about 1/8 to 3/16 in size and flat. Mostly from the shaved pinion cage
assembly.When whatever caused the lockup broke the staked dowel holding one of the pinion gears, it also jammed the cage and bent that pretty bad, as well as spinning the output shaft, causing
this. I am not sure, but the
damage to the shaft does not look that bad. I intend to try to clean it up a bit with a file and make sure the cage assembly slides freely without any diagonal movement on the shaft. Or then again, I may just go see Bruce, who has a NOS output shaft on his site right now. What's another $70, right? But, I will replace the cage with one I sourced from Obsolete Chevy.
As for the main case (and the reason for this thread), the
innards show 56 years worth of wear. The first and reverse slider gear is pretty worn and the middle gear of the countergear cluster has a few good chunks out of it. Replacing both of those.
Here's the idler gear shaft
lock pin that we couldn't find and that wasn't described in the manual...lots of fun with that part of the day.
But speaking of which, SWEET helped me pull this thing apart and we're going to have a blast putting it back together. That's what it's all about! A perfect way to spend a fall Monday off of work. Strange, though, SWEET seemed to disappear right when it came time to start cleaning all the parts...
At any rate, the input and main shafts showed no signs of wear from the bearings and the needle bearings on the main shaft looked to be in pristine condition. All good signs.
Only question I have right now has to do with the synchro drum. I don't know what the brass-looking fittings (that look like the 'dentil moulding' end of a commutator) look like when new, so nothing to compare mine to yet. Need to send up a picture of those parts as well.
I did replace the very worn output shaft bushing with a new one. MUCH less sloppy on the yoke.
Well, best get to cleaning.
Jim
